Class Cluster (2.30.0)

public class Cluster

A cluster represents the actual Cloud Bigtable service. Each cluster belongs to a single Cloud Bigtable instance, and an instance can have up to 2 clusters. When your application sends requests to a Cloud Bigtable instance, those requests are actually handled by one of the clusters in the instance.

equals(Object o)

public boolean equals(Object o)

Parameter
Name	Description
`o`	`Object`

Returns
Type	Description
`boolean`

Overrides

Object.equals(Object)

getAutoscalingCpuPercentageTarget()

public int getAutoscalingCpuPercentageTarget()

Get the cpu utilization that the Autoscaler should be trying to achieve. This number is on a scale from 0 (no utilization) to 100 (total utilization).

Returns
Type	Description
`int`

getAutoscalingMaxServeNodes()

public int getAutoscalingMaxServeNodes()

Get the maximum number of nodes to scale up to.

Returns
Type	Description
`int`

getAutoscalingMinServeNodes()

public int getAutoscalingMinServeNodes()

Get the minimum number of nodes to scale down to.

Returns
Type	Description
`int`

getId()

public String getId()

Gets the cluster's id.

Returns
Type	Description
`String`

getInstanceId()

public String getInstanceId()

Gets the instance id.

Returns
Type	Description
`String`

getKmsKeyName()

public String getKmsKeyName()

Google Cloud Key Management Service (KMS) settings for a CMEK-protected Bigtable cluster. This returns the full resource name of the Cloud KMS key in the format projects/{key_project_id}/locations/{location}/keyRings/{ring_name}/cryptoKeys/{key_name}

Returns
Type	Description
`String`

getServeNodes()

public int getServeNodes()

Get the number of nodes allocated to this cluster. More nodes enable higher throughput and more consistent performance.

Returns
Type	Description
`int`

getState()

public Cluster.State getState()

Gets the current state of the cluster

Returns
Type	Description
`Cluster.State`

getStorageType()

public StorageType getStorageType()

The type of storage used by this cluster to serve its parent instance's tables, unless explicitly overridden.

Returns
Type	Description
`StorageType`

getStorageUtilizationGibPerNode()

public int getStorageUtilizationGibPerNode()

Get the storage utilization that the Autoscaler should be trying to achieve. This number is limited between 2560 (2.5TiB) and 5120 (5TiB) for a SSD cluster and between 8192 (8TiB) and 16384 (16TiB) for an HDD cluster; otherwise it will return INVALID_ARGUMENT error. If this value is set to 0, it will be treated as if it were set to the default value: 2560 for SSD, 8192 for HDD.

Returns
Type	Description
`int`

getZone()

public String getZone()

Get the zone where this cluster is located.

Returns
Type	Description
`String`

hashCode()

public int hashCode()

Returns
Type	Description
`int`

Overrides

Object.hashCode()
